Product Description
Reactive dyes are a type of textile dye that chemically bonds with the fibers of the fabric, resulting in a long-lasting and durable coloration. These dyes contain reactive groups that react with the fiber molecules, forming covalent bonds. This unique characteristic of reactive dyes allows for excellent color fastness and wash-fastness properties.
FAQ :
Q: What are reactive dyes?
A: Reactive dyes are a class of dyes that are widely used for coloring textiles, particularly natural fibers such as cotton, linen, and rayon. They contain reactive groups, typically either vinyl sulfone or monochlorotriazine, that chemically react with the hydroxyl or amino groups present in the fiber molecules. This chemical reaction forms a strong covalent bond, resulting in excellent color retention.
Q: Can reactive dyes be used on all types of fabrics?
A: Reactive dyes are primarily designed for use on natural fibers such as cotton, linen, rayon, and silk. These fibers have reactive groups that allow for a chemical reaction with the dye molecules. However, reactive dyes may not be suitable for synthetic fibers like polyester, nylon, or acrylic, as these fibers lack the necessary reactive sites for bonding with the dye molecules.
Q: How are reactive dyes applied to fabrics?
A: Reactive dyes are typically applied to fabrics through a dyeing process known as exhaust dyeing. The fabric is immersed in a dye bath containing the reactive dye, along with various auxiliaries and chemicals to promote dye absorption and fixation. The dye bath is heated, and the reactive dye molecules chemically react with the fiber molecules, forming stable covalent bonds.
